A Methodology to Develop Extended Reality Applications for Exhibition Spaces in Museums
(Institute of Electrical and Electronics Engineers, 2022) Granda Juca, María Fernanda; Barreto Paredes, Christian Fabián; Agudo Guiracocha, Dayana Isabel; Parra González, Luis Otto; Parra González, Luis Otto
Web 2.0 brought the development of social networks and new elements of interaction that were incorporated into Web sites and devices that supported them. In the field of museums, the emergence of Web 2.0 and Museum 2.0 has made it possible to improve access to information regarding art collections. Due to the COVID-19 pandemic, museums have opted for the introduction of technology permitting virtual access to their collections. However, many applications were developed using traditional development process without considering a methodology dedicated to extended reality applications. This paper describes a methodology for the implementation of extended reality applications to exhibition spaces in museums. Using a quasi-experiment, we evaluate the data collection stage of the proposed methodology to develop an extended reality application to visit exhibition spaces in a museum. Results show that the proposed methodology helps to the software engineers/designers in the development process of extended reality applications.
Generation of Microservice Names from Functional Requirements: An Automated Approach
(Springer Science and Business Media Deutschland GmbH, 2024) Granda Juca, María Fernanda; Saquicela Galarza, Víctor Hugo; Arias Barros, Jhoan Sebastian; Suquisupa Nacipucha, Pamela Aracely
In the context of the advancement of software architectures based on microservices and the relevance of requirements engineering in application development, the problem of manual creation and the need for expertise to define microservices, a human activity that requires a high level of knowledge and experience, arises. To address this challenge, a solution is proposed that consists of finding the ideal names for microservices. To automate the process of identifying microservice names, this proposal is based on the application of Natural Language Processing (NLP) techniques, graph analysis and community detection, including the use of artificial intelligence language models such as ChatGPT.
Evaluating the meeting solutions used for virtual classes in higher education during the COVID-19 pandemic
(Institute for Systems and Technologies of Information, Control and Communication, 2021) Granda Juca, María Fernanda; Parra González, Luis Otto
When the Ecuadorian government put the country into quarantine as a preventive measure against the Covid-19 pandemic the country’s schools and colleges had been working normally up to March 2020. On March 13th, the University of Cuenca decided to suspend face-to-face classes and changed the system to virtual online teaching. Although the teachers and students changed the teaching-learning method from face-to-face to virtual, they were not prepared to continue their education in this new educational system, in which each student’s family had different mandatory elements (e.g., an Internet connection, computer, meeting solution). However, they continued the classes through meeting solutions to continue the school year through virtual classes but without any criteria to select the most suitable meeting tool. This paper evaluates two of the most commonly used meeting solutions for virtual university classes: Webex and Zoom. We used User Experience Questionnaire and Microsoft Reaction Cards to evaluate these solutions. The results showed that Zoom was significantly more attractive than Webex, although there was no significant difference between them in the classic aspects of usability or user experience.
Empirical and theoretical evaluation of USE and OCLE tools
(INSTICC, 2021) Granda Juca, María Fernanda; Parra González, Luis Otto; Vera Mejía, Carlos Darwin; Granda Juca, María Fernanda
Validating the conceptual model (CM) is a key activity in ensuring software quality and saving costs, especially when adopting any type of Model-driven Software Engineering methodology, in which standard modelling languages such as UML and tools support for validation become essential. This paper analyses and evaluates the main characteristics of the tools to support test-based validation in CMs. For this, two research approaches were used: (1) an empirical evaluation to compare the effectiveness and fault detection efficiency in a CM and analyses the level of ease of use of two tools used to validate requirements in UML conceptual models, and (2) a complementary theoretical analysis. The study focuses on the class diagram, the most common type of UML diagram, and two tools widely used by the modelling community for test-based validation: USE and OCLE. Theoretical and empirical comparisons were carried out with the aim of selecting an appropriate tool to validate UML-based CMs with OCLE achieving a better score.
Exploring Perspectives of Students on Using Mobile Apps to Improve English Vocabulary Through Youtube Videos: A Comparative Study
(Science and Technology Publications, Lda, 2024) Granda Juca, María Fernanda; Parra González, Luis Otto; Reinozo Trelles, Edisson Santiago; Parra González, Luis Otto
Currently, in countries where the mother tongue is not English language, globalization brings a very important requirement related with level of English since it facilitates communication in any area, be it, business, education, tourism, and so on. People need to have a good mastery of the English language, however, if the mother tongue is different from English, dominating the English language can become a very serious problem. Under these circumstances, in countries where the mother tongue is not English, educational institutions have included meaningful learning of English as a second language in their curriculum for many years. Vocabulary is one of the essential components of any language and it is required get a good level in order to have success in the process of teaching/learning of the English. Spaced repetition has been widely implemented and examined in mobile-assisted vocabulary learning as an important learning strategy. In this context, the purpose of this comparative study was to investigate and compare university students’ perspectives utilizing two mobile apps to improve English vocabulary in the Language Department at University of Cuenca (Ecuador): the first application is Slango and the second was chosen applying multi-criteria decision making of a set of mobile apps with similar features than Slango. Therefore, we did a comparative evaluation of the two mobile apps in order to evaluate usability by using SUS questionnaire and desirability by using Microsoft Desirability Test. Results show that Slango has similar features as ReadLang (the second app to compare) when it is used to improve student English vocabulary using YouTube videos.
Mutation operators for UML class diagrams
(Springer, Cham, 2016) Granda Juca, María Fernanda; Condori Fernandez, Nelly; Vos, Tanja Ernestina; Pastor López, Oscar; Granda Juca, María Fernanda
Mutation Testing is a well-established technique for assessing the quality of test cases by checking how well they detect faults injected into a software artefact (mutant). Using this technique, the most critical activity is the adequate design of mutation operators so that they reflect typical defects of the artefact under test. This paper presents the design of a set of mutation operators for Conceptual Schemas (CS) based on UML Class Diagrams (CD). In this paper, the operators are defined in accordance with an existing defects classification for UML CS and relevant elements identified from the UML-CD meta-model. The operators are subsequently used to generate first order mutants for a CS under test. Finally, in order to analyse the usefulness of the mutation operators, we measure some basic characteristics of mutation operators with three different CSs under test.
Evaluating Extended Reality Application for a Virtual Museum. Case Study: Remigio Crespo Museum.
(Institute of Electrical and Electronics Engineers Inc., 2023) Parra Gonzalez, Luis Otto; Barreto Paredes, Christian Fabian; Agudo Guiracocha, Dayana Isabel; Granda Juca, María Fernanda
The COVID-19 pandemic was the main reason why many organisations decided to include information and communication technologies in their processes to allow them to continue with their activities, be it providing services to users (food, medicine, etc.), training/education or disseminating culture. In the field of culture, some museums incorporated technology into their operating environment, moving from face-to-face visits to virtual visits. However, in many museums, the lack of apps designed to solve the problem of virtual visits caused some to stop receiving visitors during the pandemic. In this context, this paper describes the development of an application with a user-centred design that incorporates extended reality to allow virtual visits to the Remigio Crespo Museum in the city of Cuenca (Ecuador). The evaluation carried out to verify the application's usability and learnability is also included. The results obtained indicate that users/visitors found the application usable and easy to learn
CoSTest: a tool for validation of requirements at model level
(Institute of Electrical and Electronics Engineers, 2017) Granda Juca, María Fernanda; Condori Fernandez, Nelly; Pastor López, Oscar; Vos, Tanja Ernestina; Granda Juca, María Fernanda
We present CoSTest, a tool that supports the validation of Conceptual Schemas by using testing. The tool implements techniques for transforming instantiations from a Requirements Model into test case implementations by supporting a Model-driven architecture.
UI-Test: a model-based framework for visual UI testing– qualitative and quantitative evaluation
(Springer, 2022) Parra González, Luis Otto; Alba Sarango, Bryan Andrés; Granda Juca, María Fernanda
During the testing stage in the software development life cycle, developers can take advantage of combining the requirements specification with the testing specification. This will allow the specification of the tests to require less manual effort, since, they can be defined or generated automatically from the require-ments specification. The requirements specification will thus be based on a more structured language, gaining in quality and reducing ambiguity, incon-sistency, and inaccuracy. In this research work, the UI-Test model-based meth-odological framework and its tool support are proposed. Both of these can gen-erate evidence based on the specification of agile user stories that are used in the validation of the functional requirements that must be included in the final version of the user interfaces of the developed software. Our proposal makes use of two model transformations to obtain the test scripts from user stories that will be applied in the process using SikuliX for automated visual UI testing. The results of the empirical evaluation of the effectiveness and user experience of the framework and its tool support suggest that the UI-Test tool can benefit testers by confirming that the actions proposed in the user stories can be run on the UIs.
